Fields

key_image: KeyImage

Key Image for signed ring

c_zero: Scalar

Zero’th challenge for signed ring

Trait Implementations

impl Clone for TxKeyImage

fn clone(&self) -> TxKeyImage

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TxKeyImage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'dec> Decode<'dec> for TxKeyImage

type Output = TxKeyImage

Output type (allows attaching lifetime bounds where required)

type Error = ApduError

Error type returned on parse error

fn decode(buff: &'dec [u8]) -> Result<(Self::Output, usize), Self::Error>

Decode consumes a slice and returns an object and decoded length.

impl Encode for TxKeyImage

type Error = ApduError

Error type returned on parse error

fn encode_len(&self) -> Result<usize, Self::Error>

Calculate expected encoded length for an object

fn encode(&self, buff: &mut [u8]) -> Result<usize, Self::Error>

Encode method writes object data to the provided writer

impl PartialEq<TxKeyImage> for TxKeyImage

fn eq(&self, other: &TxKeyImage) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
